From: AES on
I can search for and Find carriage returns, tabs, etc, by checking the
"Match patterns (regex)" box and using the drop-down menu to insert
patterns (\n, \t, etc) into the "Find" field -- but I can't seem to
Replace found patterns or strings with such patterns: the "Replace with"
field won't accept patterns, and typing in \n or \t doesn't produce the
corresponding results . . . ?

Also, is there any way to select _and edit_ a link (URL) that's already
present in a document? (e.g., I'd like to shorten the name of the URL,
without changing the actual URL)
